A weak tropical storm (Gabrielle in 2001) experienced a 22-hPa pressure fall in less than 3 h in the presence of 13 m s ambient vertical wind shear. A convective cell developed downshear left of the center and moved cyclonically and inward to the 17-km radius during the period of rapid intensification. This cell had one of the most intense 85-GHz scattering signatures ever observed by the Tropi...

[1] The Multifluid‐Lyon‐Fedder‐Mobarry (MFLFM) global simulation model incorporating an ionospheric cusp O outflow model based on an empirical relation between downward DC Poynting flux and O outflow flux regulated by the precipitating electron number flux (Fen) is used to simulate the 31 August 2005 storm. A baseline run incorporating the original solar wind data is contrasted against a case w...

The solar{wind driven magnetosphere{ionosphere system is a classic example of a complex dynamical system (CDS). The de ning properties of a CDS are (1) sensitivity to initial conditions; (2) multiple space{time scales; (3) bifurcation sequences with hysteresis in transitions between attractors; and (4) noncompositionality. Noncompositionality means that the behavior of the system as a whole is ...

In this research the behavior of small-scaled wind turbine system is evaluated against strong wind input considering round trip delay. Generally, the wind turbine system is generating energy from the revolution of blades. The revolution of blades is depended on the velocity of wind. Therefore, if there is strong wind then the revolution of blade is increased and more energy will generated. Ther...

A database of tropical cyclone best track and intensity information for the southwest Pacific Ocean basin is used to construct a 28-year climatology for tropical cyclones that move into middle latitudes. Of the nine or so tropical cyclones that form each year, an average of about three can be expected to migrate south of 358S, with the greatest fraction in March. Storms entering the Tasman Sea ...

[1] Most recent studies of tropical cyclones and their relationship to changing environmental conditions, including sea surface temperatures (SST), have examined regionalscale seasonal averages in comparison with basin-wide seasonal tropical cyclone characteristics [e.g., Emanuel, 2005; Webster et al., 2005; Hoyos et al., 2006]. In our recent paper [Michaels et al., 2006], we took a different a...

Upper-ocean heat and mass budgets are examined from three snapshots of data acquired during and after the passage of Hurricane Gilbert in the western Gulf of Mexico. Measurements prior to storm passage indicated a warm core eddy in the region with velocities of O(1) m s21. Based upon conservation of heat and mass, the threedimensional mixed layer processes are quantified from the data. During a...

The effects of the 31 March 2001 severe magnetic storm on the Southern Hemisphere ionosphere have been studied using ground-based and satellite measurements. The prime goal of this comprehensive study is to track the ionospheric response from high-to-low latitude to obtain a clear understanding of storm-time ionospheric change. The study uses a combination of ionospheric Total Electron Content ...
